🔍 Key Concepts

• Source vs. transmission of vibration in marine diesel installations • Difference between devices that control crankshaft torsional vibration and those that isolate vibration from the hull • How engine mount design affects noise and vibration felt in the ship’s structure

💭 Think About

• Which choice specifically deals with stopping vibration from being passed into the ship’s structure, rather than controlling vibration inside the engine itself? • Look at each option and ask: does this part bolt to the crankshaft, or does it sit between the engine and the hull/foundation? • On a ship, what component is usually made of rubber/elastic or spring elements to reduce noise and vibration transmitted to decks and bulkheads?

✅ Before You Answer

• Identify which options are crankshaft-related devices versus support/installation-related devices • Think about what is normally placed between the engine bedplate and the foundation/hull • Verify which item’s main purpose is to reduce vibration and noise transmitted to the ship’s structure, not just to protect the crankshaft
